[Don Shigeru] Parasiter Miki Chapter 5

Dr. Miki, a bespectacled scientist running tests on the parasite subject Harumi, discovers the organism's unsettling ability to replicate a host's body and mind while sustaining devastating physical damage. When Harumi emerges from captivity transformed into a futanari doppelganger with an insatiable lust, she turns the tables on her captor, pinning the buxom doctor down and forcing her into a machine-assisted ordeal as armed guards close in. The tension between violated victim and violated scientist blurs into something far more dangerous as control slips entirely from the lab's hands.
